You're bored son? I know it's raining outside and you can't do much. Mommy laughs thinking of a game she used to play. Son asks what mommy was thinking about. Mommy tells son she used to play a game in school. Mommy would edge the boys till they HAD to cum. It's inappropriate for us to play son. I shouldn't have said anything. You really want to play son? Are you sure? Okay, it is wrong for us to play, but it'll be fun.
